I view CloudStack from ‘What can cloud consumers practically do with it’ point-of-view

What’s New in Apache CloudStack 4.5

765 fixes/features Integration with external DNS Provider (Bind, PowerDNS) Nuage VSP Network Plugin vGPU Enhancements SAML 2.0 Integration Linux Containers (RHEL 7) MySQL 5.6 (RHEL 7) XenServer 6.5 support Improved VM Sync for vSphere Enhanced SolidFire integration Domain/Account/User Sync Up Among Multiple Regions Improved CloudByte Storage Plugin for 4.5 and above.

What’s New in Apache CloudStack 4.5

Summary: Bind9 or PowerDNS new Network Service Provider called GloboDNS new Network Element to manage network domains and VM records

(entries) on an external API new Network Resource to communicate with GloboDNS (open

source) new API command to add DNS server new global option to determine if this provider should override VM

entries on external DNS server changes in UI to include GloboDNS in Providers list

Integration with External DNS

Support for LXC ‘hosts’ on RHEL 7. NFS, local storage and RBD (Ceph) is supported for Primary storage. Beware, unavailable features:

Console access Live migration Migration across clusters Storage migration Snapshots Uploading and downloading volumes Template creation from ROOT volume ISO support for creating VM

Linux Containers

64 bit dom0 removes the limitations of Linux low memory and allows the use of modern drivers and works better with modern servers

The move to a 3.10 kernel from kernel.org means the kernel is no longer a completely custom kernel

The move to the Xen Project hypervisor 4.4 is the most stable version of the core hypervisor available.

Updated OVS to 2.10 virtual switch giving improved network stability when the virtual switch is under pressure.

A thread per vif model was introduced to better ensure network hogs didn't impact adjacent VM performance

Network datapath optimizations can drive line rate for 10Gbps NICs, and close to line level with 40Gbps NICs.

Storage improvement through an update to tapdisk3. Delivering very significant improvements in aggregate disk throughput

XenServer 6.5 support

Multiple SolidFire SANs supported in a single CS Cloud

Add Primary Storage based on SF Plug-in via GUI

Shared-IOPS Plug-in

Resize Volume (IOPS and Size) - (KVM limited to modifying IOPS only)

Enhanced SolidFire integration

Enables single sign-on and single sign-off across multiple applications

SAML 2.0 Integration

The Nuage Networks™ Virtualized Services Platform (VSP) is a Software-Defined Networking solution that virtualizes any datacentre. It deploys the full range of L2-L4 networking services on a per-tenant or per-application basis using overlay technologies.

Network isolation and routing is handled by the Nuage SDN solution. Routing of the packets happen at hypervisor itself. Virtual Router is not used for routing the

packets. NuageVsp plugin supports the following network model / service combinations: Advanced Isolated networks

DHCP Static NAT Source NAT Firewall

VPC network mode: DHCP Static NAT Source NAT Network ACL

Nuage Networks Plugin

Adds improved support for XenServer VDI deployments

GPU-passthrough or vGPU support

Supports up to 96 vGPU accelerated VMs (XenServer 6.5)

Requires NVIDIA GRID Kepler 1 and 2 series

vGPU Enhancements

A new plug-in enables automatic VLAN programming on a physical switch to which baremetal instances are connected. In an Advanced zone, Baremetal instances gain VLAN isolation

Baremetal As a Service works in conjunction with a physical switch either from vendor's SDK or from an in-switch agent for white box switch.

Advanced Networking in Baremetal
